The new VT3100 from Yokogawa Martron is a transport stream monitoring station for the monitoring, recording and playback of transport streams in digital TV broadcasts.

The instrument is a self-contained benchtop unit incorporating all the necessary monitoring, triggering, recording and playback functions required for digital content supervision and troubleshooting.

The VT3100's triggers include a 4byte data-pattern trigger and TMCC trigger for supervising digital satellite TV broadcasts, as well as triggers for detecting the events defined in the ETR290 standard.

Up to three channels of streams can be monitored independently.

Filters are included for extracting and recording specific transport streams, and a web browser function allows transport streams to be monitored remotely.

By simply connecting the instrument to an Ethernet network, a Web browser running on any PC can be used to view the recorded streams and TMCC tables from anywhere.

A wealth of playback functions is provided for reproducing and verifying problems, including those requiring playback of a large content or repeated playback of the same content over a long time.

The playback rate can be varied from 100Kbit/s to 56.61Mbit/s, covering all applications from data broadcasting to HDTV.
